Some questions about mapping

Hi, I have some little questions about mapping:

is it possible to add this face in the basement of the house, and after every 30seconds this face appears ? ( the map i m making is like a house in real life )

I want to make someone like this guy outside the house, I make it for scaring players, And I want this guy to move his hands, is it possible to make this?

You can make the face a func_train and put it on a track in a room you can't get into. Have just one of the path_track points be inside the map where you want it to show up. It can teleport if you don't want to see it moving.
